Qi Wireless Charging – from Nikola Tesla to Wireless Chargers
Why use Qi Wireless Charging? Modern technology ensures that our world is increasingly being freed from cables. With Wifi or Bluetooth, it has been possible to transfer data wirelessly for many years. But although Nikola Tesla was able to successfully transmit electricity via induction wirelessly more than 100 years ago, this technology is still hardly found in everyday life, except for electric toothbrushes. This is currently changing a lot and many are recognizing the convenience of induction chargers or a Wireless Charger with Qi standard. Here you can find all relevant information on this topic. Wireless Charging is a relatively new standard and there are a few things to consider. In the comparison test we only look at bestsellers and well-known products, but also at the cheaper models from the field of inductive chargers and collect all the important information about the respective product. Inductive charging is also increasingly a topic in the media, which is why we would like to keep you up to date with the “News” category.
How does Wireless Charging work?
The charging station generates a small electromagnetic field a few millimetres above the charging surface as soon as a compatible device is detected. The inductive energy exchange between the transmitter and receiver coils begins. The receiver coil transfers the current to the battery and the battery charges. The charging process is continuously monitored and automatically terminated as soon as the battery is fully charged.
What is the Qi Standard?
Qi-Standard is a standard for wireless power transmission, also called inductive charging – currently mostly used in mobile phones & smartphones. It was developed by the WPC (Wireless Power Consortium) in 2008 and since then has established itself as a member of the market with over 200 companies and has prevailed over the competing PMA standard. The Qi standard is not restricted to specific devices or manufacturers, but is compatible throughout. This means that a Qi charging station from a specific manufacturer can basically be used to charge all Qi compatible devices. Wireless charging is basically interoperable.
However, there are differences in quality, as with any product class. Current top models in the field of induction chargers are usually made by Samsung. With the Samsung Galaxy S6, the manufacturer was already firmly committed to the wireless charging standard and has since then launched a separate Qi charger for each model. The Samsung Wirelss Charger models are often among the bestsellers in this product class.
Qi Charger: Experience & Purchase Advice
There is already a quite respectable choice of wireless chargers according to the Qi standard, also called Wireless Charger. But especially for the layman a comparison is often not easy. In our test report summaries, all important questions are answered and in the comparison table for Qi chargers you can get a quick overview of the range. In addition to the chargers, this website also covers the technology itself, the technology behind it and our own experiences in handling it. Everyone can inform themselves about the advantages and disadvantages of the Qi standard and the topic of “wireless charging” or inductive charging (blog article: What is the Qi standard) and decide for themselves whether a purchase is worth considering.
Whether your smartphone can be retrofitted with the Qi-Standard or already supports it, you can find out in the list of Qi phones. Other Qi-certified devices or those with wireless charging function such as monitors, All-In-One-PCs or Bluetooth speakers or Smartwatches already exist and are collected below this list. Smartphones that are not directly intended by the manufacturer to be retrofitted with the Qi standard can be retrofitted using a universal Qi receiver with a micro-USB connection and then also recharged using an inductive charger. Test summaries also do not shy away from criticism: If a certain device cannot meet the requirements of everyday life, this becomes clear to the reader. We are a manufacturer-independent platform that wants to offer its readers objective reporting. Because wireless charging does not only have advantages – more on this in the following sections.
What is a Qi Wireless Charger?
A Qi wireless charger is a charger for smartphones and other small devices that uses induction to transfer power wirelessly. So-called induction coils are used, which can transfer energy via an electrical field. With Qi chargers, it is advantageous, among other things, if several of these coils are installed. This makes handling easier, as the device placed on top of the charger is recognised more quickly and exact positioning is no longer necessary. However, wireless charging varies in speed, so the power level of the charger is important when purchasing.
Otherwise, Qi chargers are usually offered in a flat form or as a standalone device – special forms are for example Qi holders for cars or Qi Powerbanks. In general, models from well-known manufacturers are usually the better choice, as they are usually among the more sophisticated Qi chargers. Some have also been specially designed for certain mobile phone models. The current power levels for a Qi charger are 5W – 7.5W – 10W. Modern designs support all three modes and select the appropriate power level for each phone model. However, most of them do not belong to the cheap Qi chargers on the market. You can also find more detailed information about important criteria when buying a Qi charger in the comparison table in the section “What do I need to compare with a Qi charger?
What do I have to pay Attention to when Buying?
Wireless charging by induction With the Qi charger comparison you can basically orientate yourself on the following points in order to make the right choice quickly:
- Performance: Current Qi chargers charge with 5W, 7.5W or 10W – also depending on the respective smartphone.
- Design: Most models are flat or designed as standalone devices.
- Technology: Several induction coils facilitate handling.
- Manufacturer: Well-engineered models are available from Samsung, Anker or Belkin
- Scope of delivery: Qi chargers are often delivered without power supply – check if you need one.
Inductive Charging: Advantages and Disadvantages
Pros: What are the advantages?
- Very practical in everyday life
- No wear of the connections
- Manufacturer independent standard, suitable for Apple & Android
- Distribution in public places (bars, cafes, airports & hotels)
- More safety compared to cable in public places
Cons: What are the disadvantages?
- Charging takes a little longer & power consumption may slightly increases
- Retrofitting is necessary for some devices
- Direct contact with the charger is necessary
- Thicker protective covers must be removed during loading
The advantages of wireless charging stations are clearly in their easy handling. You no longer have to bother to connect the USB plug to the mobile phone, but simply place or set it down on the Qi charging station – the charging process begins. A further advantage is that the plug connection on the mobile phone does not wear out unnecessarily. A side effect: Due to the easier handling in everyday life, you usually charge your smartphone more often (in a more tolerable charge level for the battery) and thus have more energy available throughout the day.
The disadvantage of charging by induction: The transfer is not possible without energy loss. A small part of the electricity is converted into heat. The smartphone or Qi charger can heat up slightly as a result, which is why some models with the so-called “Fast Wireless Charging” Qi standard have a small fan installed for cooling. This ensures that the temperature of the device or battery is always within an optimal range. Qi chargers with a fan have been put together separately.
Design: Wireless Charging Station or Flat Charging Pad?
An upright wireless charging station is, in addition to the flat design, the most common type of inductive charging devices according to the Qi standard. It allows you to keep an eye on the display of your smartphone, for example at your desk, even during the charging process. This already indicates the primary area of application: At the desk in the office or at home. Flat Qi chargers or wireless charging mats are therefore more suitable for the bedside table or other places where you just want to put the device down. Cordless charging stations often have several induction coils built in because they offer more space. In addition, the smartphone can charge wirelessly while standing or lying on its side. Well-known manufacturers, such as Anker or Samsung, always have an upright charging station in their range of wireless charging mats. Special forms of wireless charging stations are those that can charge several devices at the same time – also known as dual charging stations. They are available for Smartphones as well as for the combination with wearables, such as a Smartwatch or the AirPods charging station. Some models allow up to three devices to be charged simultaneously with a single wireless charging mat.

Qi Chargers for Apple iPhone and Android
When Apple finally decided to use the Qi standard or inductive charging with its iPhone, a wireless charger, the iPhone Qi Charger Belkin Boost up 7.5W, was developed in cooperation with the company Belkin. In the future, it is estimated that there will also be in-house Qi chargers from California. After all, Apple already relied on wireless charging technology for its Apple-Watch, but in this case according to a specially developed wireless charging standard. Basically conceivable, and already implemented in earlier models, is an induction charger for wireless charging of several devices at the same time. Qi chargers for Smartphone and Smartwatch, which can be charged at the same time, are also already on the market. Wireless charging on the iPhone is currently supported in the power levels 5 watts and 7.5 watts – see the link below for more information. Various Qi chargers for Apple iPhones can be found here.
Samsung with its smartphones based on the Android operating system was not a pioneer, but has been the market leader in the field of inductive chargers for years. The Qi charger, which is released with every new Galaxy series, has always been a fast seller in the field of induction chargers on amazon.de. Samsung models can also be recommended here – and of course for all other Qi mobile phones.
AirPower Alternatives: No Apple Wireless Charger available
Unfortunately there will be no Apple charging mat according to the Qi standard for the time being, which is why many are looking for AirPower alternatives. The development of the long announced and highly anticipated AirPower charging station has been officially stopped. The reasons for this can only be speculated, as there was only a short statement from Apple. The special thing: Up to three devices should be able to be charged wirelessly with AirPower. But other manufacturers also offer this service and have brought reliable AirPower alternatives onto the market.
Wireless Charging: permanent Trend or short Hype?
The convenience of wireless charging can be seen as a clear advantage and will further advance the technology already established elsewhere. With Apple’s decision for the Qi standard and its installation in the entire iPhone 8 model range, this path is already pre-programmed. Wireless charging is on the advance. At least for the time being, Samsung still dominates the market and offers mature Qi chargers. But other manufacturers, such as Anker or Belkin also offer reliable models. The comparison is worthwhile!
Tips for finding the Best Wireless Charger
- There are currently three performance levels: wireless chargers according to Qi standard 1.1 (5 watts), Qi fast chargers according to Qi standard 1.2 with 7.5 watts for new Apple iPhones and with 10-15 watts for newer Samsung models.
- Pay attention to the addition “Fast Wireless Charging” (downward compatible)
- Several induction coils inside (mature models) make handling much easier
- inductive chargers can be used with all Qi compatible devices
- it is important to use a sufficiently powerful USB power supply recommended by the charger manufacturer (mostly 5V / 2A)
- Due to this still young product class, bestsellers and well-known manufacturers are usually the better choice
- good devices are offered by e.g. the following manufacturers or brands known in this field: Samsung, Anker, Nokia, Belkin, Nanami, Hama, Ikea or Zens.
- Induction chargers are often delivered without a power supply unit (visible in the scope of delivery!). The reason: These are usually available anyway – but you should check if it is powerful enough. Which power supply is needed can be seen in the respective product description of the dealer – mostly 5V / 2A or 9V / 1.67A.
Charging without Cables – Wireless Chargers on the Advance
Charging without cables or inductive charging has many advantages and is simply practical, which is why we believe it will continue to gain acceptance. It will not only become more widespread in the home, but also in the working environment or in public places such as cafés or airports. Whether a Qi charger and the associated charging without cables is beneficial for you personally is ultimately a matter for everyone to decide for themselves. We will give you an overview of the market and help you choose the right wireless charger.
